摘　　要：本文建立了汽油机在加速工况时缸内工作过程计算模型,应用理论方法对缸内工作过程进行了较为详尽的描述,编制了计算程序,其计算结果与试验结果基本吻合,为解决汽油机在瞬态排放及其设计方面提供了较好的依据。A model for working process simulation of gasoline engines was developed under transient conditions. Therefore, the working process of gasoline engines could be described on theoretical basis. The computer program was edited. The results of simulation are agreed perfectly with that of test, and can provide support for design and study of transient emissions.
